Efficacy of Different Entomopathogenic Fungus on Chilli Thrips

A field experiment was carried out at College Farm, N. M. College of Agriculture, N. A. U., Navsari (Gujarat) during Rabi 2014–15. The efficacy of different entomopathogenic fungus viz., Beauvaria bassiana 0.4 per cent, Metarhizium anisopliae 0.25%, Verticillium lecanii 0.4%, Nomuraea rileyi 0.1% against chilli thrips. Among the four entomopathogenic fungus Beauvaria bassiana 0.4 per cent was found to be most effective against thrips and recorded the maximum fruit yield of chilli (145.6 q/ha). The highest cost benefit ratio (1: 15.90) was obtained with treatment Metarhizium anisopliae 0.25% and it was followed by Verticillium lecanii 0.4% (1: 12.77), Nomuraea rileyi 0.1% (1: 9.88) and Beauvaria bassiana 0.4% (1: 6.77).
